Application filed February 11, 1924. Serial Mo. 692,000.

To 6! who/1t it may concern.

Be it known that I, rimmer H. .Grnns, a citizen or" the United States. and resident of M ilwaulreo. in the coiilnty ot Mili 'aukee and State of lVisconsin, have invented new a1 it useful Improvements in Sectional Hiranmes, of which the following is a description. reterence being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in hammers and more particularly to sectional hammers. It is one of the objects of the present invention to provide a hammer so constructed that the contact portions may he replaced when they have become worn or are unlit for further use.

A further object of the invention is to provide a hammer constructed to permit in terchangeability of the contact portions so that the hammer may be used for many forms of work.

A further object of the invention is to provide a hammer which can be entirely disassembled to permit replacement of any of its parts. i

A further object of the invention to provide a hammer which is of very simple construction, is inexpensive to manufacture, is strong and durable, and is well adapted for the purpose described.

lVith the above and other objects in view the invention consists of the improved sect ional hammer and its parts and combinations as set forth in the claims, and all equivalents thereof.

I In the accompanying drawing in which the same reference characters indicate the same parts in all of the views;

Fig. 1 is a side view of the improved sectional hammer;

Fig. 2 is a sectional view thereof taken on line 22 of Fig. 1;

Fig. 3 is a side view of one of the head sections of the hammer;

Fig. 4: is a side view of one of the contact portions; and

Fig. 5 is a view of another "form of tool adapted to be used in place of the contact portions.

Referring now more particularly to the accompanying drawing it will be seen that the numeral 8 indicates the improved sectional hammer, the same comprising generally a head portion 9, contact portions 10, and a handle or shank 11.

12 of the handle.

The handle or shank 11 is elongated and tubular in form and may be construe from piping or the like. One end portion thereof formed with a pair of oppositely disposed lips 19., the purpose of which will be explained hereinafter. i

The head portion 9 is composed of a pair of complementary, similarly constructed sections 13 and 13 formed as shown in Fig. with longitudinal grooves 14% and transverse grooves 15.

The contact portions 10 are two in number and are shaped as shown in Fig. l with enlarged, tapered contact ends 16, of circular cross section, and stem connecting portions 17. The outerends of the stem connecting portions are flanged or enlarged as at 18. The contact portions may be formed of brass, lead, babbit, or any other similar de siralcle material, depending upon the use to which the hammer isto ,be put. l Vghen the members 10 are constructed of metal it has pouring the metal in suitable molds.

' lVhen the hammeris assembled, the lipped end of the handle is fitted into the groove 15 of one of the head sections as 1.3." It will be noticed that each head section above and below the inner ends of each groove 15 to form with a half recess 15 .(see particularly Fig. 3) which, when the .two sections of the head are adjusted together form small rebeen found convenient, to cast the same by cesses to receive the lips 12 ot the handle.

It will be noticed that each head section ,is formed with a half recess 15' above and below the inner ends Off each groove 15, (see particularly Figure 3) and when the two sectionsof the head are adjusted together, small recesses are formed to receive'the lips The contact ends 10 are then placed in the longitudinal grooves 14:,

"the stem connecting portions 17 being received thereby and the portions 16 thereof projecting outwardly fronrthe ends of the sections 13 forming continuations. It will be noted that the longitudinal grooves 1 1 arev recessed as at 1.8 to receive thetlanged ends 18 and in this manner the contact mem bers are retained in'position and are held against longitudinal moven'ient. The tapered portions 19 ot the grooves, adjacent the recesses, afford play for the flanged ends 18 should they become misshaped from use and pounding. After the handle and contact ends have been positioned in one of the secv tions, as explained, the other head section 13' is placed thereon and the complementary grooves l t and 15 will surround the portion of the handle and the contact meinbe s d said members will be enclosed within head sections. The head sections are provided with complementa y bores 20, a portion of one bore being threaded, and a bolt 21 is passed tl erethrough to tirmig, loch the sections together, as shown.

Obviously, when the contact ends become worn they may easily be replaced and the device has the added advantage that vario s forms 03: contact ends may be substitnt depending upon the nature of the nor thereby making the hammer or great utiit Although the device has been described as comprising a hammer, it should be understood that it can be used as a tool holder, in which case a tool, as for instance the chisel illustrated in Fig. 5, is formed with a shank 17. The tool may then be substituted for one of the contact ends and the shank will be held between the head sections.

From the foregoing description it will be seen that the improved sectional hammer is of very simple and novel construction, and is well adapted for the purpose set forth.

What I claim as my invention is:

1. In a sectional hammer, the combination of ahead portion consisting of sections, each having a groove extending longitudinally thereof, said grooves registering with each other, when the head sections are adjusted together in order to form a complete recess, said head sections also provided with grooves at right angles to the longitudinal grooves, the said grooves forming acomplete recess, when the head sections are adjusted together, and each provided with small grooves extending from the inner ends thereof and at right angles thereto, each forming small complete recesses when the head sections are adjusted together, a handle provided with lips or projections, the said handle fitting the registering grooves which are at right angles to the longitudinally disposed recesses and said lips fitting the small registering recesses, when the head sections are adjusted together, contact ends clampingly engaged by the registering longitudinal grooves of the head sections, when said sections are adjusted and held together, and means for holding the head sections together.

2. In a sectional hammer, the combination of a head portion consisting of two sections, each having its inner face grooved longitudinally from opposite ends inwardly, the inner end of each groove at a desired point inwardly being enlarged, and inwardly beyond the enlargement being c011- tracted, the surrounding wall of the contracted portion being tapered, and the said grooves of the respective sections, when said sections are adjusted together, forming recesses, the surrounding wall of each recess being a complete or uninterrupted wall, and said head sections also provided with grooves at right angles to the longitudinal grooves, the said right-angularly disposed grooves forming a complete recess, when the read sections are adjusted together, and being each provided with small grooves e2;- teuding from the inner ends thereof and at it angles thereto, and forming small .nplete recesses, when the head sections are adjusted together, a handle provided with lips, said handle fitting the registering grooves which are at right angles to the longitudinally-disposed recesses, and the lips ot the handle fitting the small registO1'l11, grooves, when the head sections are adjusted together, contact ends, the outer enlarged striking heads thereof provided with reduced inwardly-extending stems, each stem at its extremity being arovided with an enlarged flanged portion, said stems, when the sections are adjusted together, fitting .in the recesses formed by the longitudinal grooves, and the flanges of the stems fitting in the enlarged portions of said grooves, said stems and flanges being completely surrounded by the uninterrupted walls of the longitudinal recesses, and means for securing the sections of the head together.

3. A sectional hammer, comprising a tubular, metallic handle formed with lips at one end thereof, a pair of complementary, metallic head sections having complementary communicating longitudinal and trans verse grooves, a pair of non-elastic metallic contact ends formed with enlar ed portions and stems, the contact ends being formed of a metal ditlering from that of the handle and head sections, the lipped end of said handle and the stem portions of said contact ends being positioned between said head sections within the grooves therein, and a bolt passing through said head sections detachably securing them together.

l. A sectional hammer, comprising a handle formed with lips at one end thereof, a pair of complementary head sections formed with complementary grooves, 21 pair of contact ends, and means for clamping the lipped end of the handle and the contact ends in position within said grooves and between said head sections, the lips on said handle cooperating with the sides of said grooves to prevent longitudinal movement of the handle.

In testimony whereof, I afiix my signature.
